Sticky notes are fine for temporary files, but do NOT use them on family treasures like photographs, bibles, clippings and letters.

How bad is it to have post-its on the back of photos? The photos are inside archival clear sleeves, along with a post-it on the back. Thanks for any input….Linda

Leaving Post-it notes or any adhesive materials directly on photographs can be destructive. If using post-its is your method of identification then the notes should be placed on the outside of the sleeves, not directly on the photographs.

The University of North Carolina (UNC) has a fantastic preservation program with a strong emphasis on public education. They state unequivacably that sticky notes are destructive to books.
